Create Technical Checklist

Use

To create a technical checklist that covers two states:

·         State of the system before the production conversion

·         State of the system after the production conversion

 

Prerequisites

Task Review Conversion Timing and Planning completed

Procedure

1.       Document the state of the system before the production conversion:

-         Specify how to get system in a clean state for the production conversion. Because test conversions may have been performed on the production hardware, it may be necessary to restore an initial backup and transport changes made to the system since the backup.

-         Estimate the disk space required for the conversion.

-         If necessary, clear directories with old logfiles from previous conversions.

-         For performance reasons, you may wish to change some operating system, database, or application parameters.

-         Specify any interfaces that must be stopped.

2.       Document the state of the system after the production conversion:

-         Check that all the conversion jobs finished sucessfully.

-         Reset the operating system, database, and application parameters to the values appropriate for production start.

-         Make sure that there is enough disk space for the first days of production operation.

-         Verify that the interfaces are up.

-         Perform any post-conversion activities, such as manually correcting some data or adapting interfaces.

-         Check that all monitoring tools are in place.

-         Make an initial backup of the system.
